Was just chatting to one of the blokes at work, he was wondering if the bar is mounted separately to the winch?
Not able to look at the car now, but the mount looks to be in two pieces. Is the inner plate part of the winch mount, and the outer plate part of the bar?

If I'm able to remove the bar with the winch in place I could drop the vertical rollers and get a socket on the fairlead bolts.
